LANGVANDLOF BABBERTON, OHIO, .ASSIGNORS TO THE BABCOCK & WILCOX COMPANY, OF BAYONNE, NEW J' ERSEY, .A CORPORATION OF NEW JERSEY ECONOHIZER TUBE SUPPORT Original application tiled January 11, 1928, Serial No. 245,970. Divided and this application Bled June 20,

- L v 1929. Serial No. 372,332.

This invention relates to an economizer in which the ends of the tubes are connected by return bends in such a manner that the joints are outside of the economizer walls.

This is a division of our application Serial No. 245,970, filed January 11, 1928, (Patent 1,818,769, granted August 11,-1931) and will be understood from the description inconnection with the accompanying drawings, in

which Fig-1 is a vertical section through an illustrated embodiment of the invention.

Fig. 2 is a horizontal section partly broken away, taken along the line 2-2 of Fig. 3, and Fig. 3 is a section taken along the line 3--3 of Fig. 2.

In the drawings, reference character 1 indicates rows of economizer tubes. Ihe end walls 3 of the economizer are provided with holes through which the tubes 1 extend. A row of holes 4 is provided in supports near the middle of each side wall of the economizer through which holes the ends of supports 5 for the tubes 1 extend. A casing 6 is spaced a shortdistance from the walls of the economizer and return bends 8 are located inside the casing and outside of the economizer walls, and connect the ends of each row of tubes to the ends of the next row, the tubes beino staggered withv respect to each other, as in icated in Fig. 3. t

The holes 4, through which the ends of the supports 5 extend, are provided in columns 9 along the sides oi the economizer. The supports 5 for the tubes 1 are made up of pairs of strips 10 and 1.1 side .by side, that are provided with notches 12 along their upper edges. The notches 12 are somewhat deeper than half the diameter ofthe tubes 1, and one end of each notch 12 in the strip 10 is provided 4with an overhanging lip 13 and the other ends of the notches 12 in the strip 11 are left with a similar overhanging lip, so that, when the strips are moved in opposite directions with the tubes 1 in the notches 12, the tubes will be clamped in place so as to prevent lateral'movement of the tubes with respect to the supports 5.

The strips 10 and 11 lare provided with transverse rectangular openings 14, so that .p

Plates 17 and side me bers 18 close the spaces beyond the ends of t e supports 5 and prevent gases from escaping through the openings 4 through which the supports 5 extend.

We claim 1. In an economizer, a row of tubes, a support for intermediate portions of said tubes, said support extending loosely through the sides of said economizer, and means to prevent leakage beyond t-he ends of said support.

2. A support for tubes comprising a plural. ity of bars movable longitudinally with respect to each other and each having tube re ceiving notches along a margin, each of said notches having a straight side and a curved' side with the straight sides of the notches in one bar corresponding to the curved notches of the adjacent bar.

3. A support for tubes comprising a plurality of bars movable longitudinally with respect to each other and each having tube receiving notchesalong a margin, and means to adjust said bars longitudinally with respect to each other and maintain them i n their adjusted position with tubes clamped 1n said notches.

4. A su port for tubes comprising a plurality of bars movable longitudinally with respect to each other and each having tube receivingnotches along a margin, and means to adjust said bars longitudinally with respect to each other and maintain them in their adjusted position with tubes clamped in said notches, said means comprising a wedge and a bolt.

5. In iuid heatexchange apparatus, a casing having openings along one side, rows of spaced iuid conducting tubes extending through the casing and being in heat exchange contact with hot gases passing ,through the casing, tube spacers eachvcomprising relatively movable clamping, strips inserted through the openings and between the rows of tubes, tube Clamping formations on the strips adapted to' have locking and embracing engagement with the tubes when lthe strips are moved lengthwise relative to each other, and means accessible from the exterior of the casing for moving the strips relative to each other and for lockingthcm in the tube clampl of tubes, tube clamping formations on the strips adapted to have locking and embracing engagement with the tubes when the strips are moved lengthwise relative to each other,

means accessible from the exterior of the cas' ing for moving the strips relative' to each other and for-locking them in the tube clamping relation into which they are moved, and a removable cover extending over the strip ends for preventing the escapeof the hot gases from the casing.

7. In fluid heat exchange apparatus, a casing having an opening along one side, a row of spaced Huid conducting tubes extending through the casing and being in heat exchange contact with the hot gases passing through the casing, a tube spacer comprising relatively movable clamping strips inserted through the opening, tube clamping formations on the strips ad apted to have locking and embracing engagement with the tubes when the strips are moved lengthwise relative to each other, and means for moving the strips relative to each other.

8. In iluid heat exchange apparatus, a cas- 4 ing having openings along one side, rows of spaced Huid conducting tubes extending through the casing and being in heat exchange contact withv hot gases passing through the casing, tube spacers each comprising relatively movable clam ing strips inserted through the openings an between the rows of tubes, tube clamping formations on the strips adapted to have locking and embracing engagement with the tubes when the strips are moved lengthwise relative to each'l other, a wedge passing through the strips for moving the stripsrelative to each other, and means for locking the strips in the tube clamping relation into which they are moved.

9. A row of spaced members, a multi-part spacer extending transversely of said members, marginal formations on parts of the p spacer presenting spaced marginal notches wide enough to allow the spacerto be moved bodily transversely of the row to position the members inthe notches, and means for moving some of said formations to cause the members to .be tightly clamped and embraced by the formations.'
